Report on New Capabilities for the Purple Development Environment

PDF Version Also Available for Download.

Description

As part of the deliverables for the Development Environment for Purple, additional capabilities to improve the tools offerings and to address unique Purple system requirements, such as increased processor count, were expected. This report details some of the new capabilities that have been incorporated into the development environment tools for Purple. The shift on Purple to 64-bit applications (from 32-bit on White) initially broke many debugging and memory tools. Most tools were updated to support 64 bit well before Purple was delivered to LLNL, but the company that provided the popular heavy-weight 32-bit AIX memory tool, ZeroFault, was reluctant to ... continued below

This report details some of the new capabilities that have been incorporated into the development environment tools for Purple. The shift on Purple to 64-bit applications (from 32-bit on White) initially broke many debugging and memory tools. Most tools were updated to support 64 bit well before Purple was delivered to LLNL, but the company that provided the popular heavy-weight 32-bit AIX memory tool, ZeroFault, was reluctant to port to 64 bit due to perceived lack of market. LLNL tried offering financial incentives to the ZeroFault developers, which were turned down, but eventually they did give vague promises to try to port to AIX 64-bit mode when they got time. The ZeroFault developers have been making intermittent and very slow progress over the last two plus years, but despite getting close, have not released a version of ZeroFault that yet meets our needs for 64-bit applications. However, given the critical need for memory tools and the uncertainty of ZeroFault development, other memory tool options were actively pursued and delivered.
